Hydromechanical Variable Transmission

TIER 4

As TIER 4 Final becomes valid in 2014, only around 10% of today's soot and NOx emissions will be permitted. This will require comprehensive exhaust gas treatment. As a supplier, Dana Rexroth Transmission Systems is also involved with these challenges, focusing on being an expert solutions partner for Original Equipment manufacturers.

TIER 4 Final Solutions Using HVT

HVT helps machine manufacturers more easily meet the future limits of TIER 4 Final. This can be achieved by downsizing the diesel engine and by optimizing the operating point. As a result, the work demand is managed even at reduced diesel engine speeds.

Applications

The idea of a power split transmission comes originally from tractor applications, whereas Dana Rexroth Transmission Systems has transferred this technology to additional application groups through modular design of the HVT. These applications include:
